Organic light-emitting display apparatus and method of manufacturing the same

A method of manufacturing an organic light-emitting display apparatus, the method comprising:

• forming a first electrode pattern on a substrate;
• forming a second electrode pattern on the substrate;
• forming an insulating layer on the substrate, the insulating layer comprising a hole exposing an upper surface of the first electrode pattern and contact holes exposing an upper surface of the second electrode pattern along an edge area of the second electrode pattern;
• forming the pixel electrode from the first electrode pattern;
• forming a cathode bus line and a first auxiliary electrode from the second electrode pattern;
• forming a second auxiliary electrode contacting the first auxiliary electrode via the plurality of contact holes;
• forming a pixel-defining layer exposing a part of the pixel electrode and the cathode bus line;
• and
• forming a cathode electrode on the pixel-defining layer so as to contact the cathode bus line, the cathode electrode configured to operate as a common electrode.
